AUTOMATIC srnlrrme AND rxr rme nnvrcn.

Patented Sept. 9, 1919.

Application filed June 5, 191-5. Serial-No. 32,428.

To all whom it may concern: i

Be it known that I, Tl-[OMAS C. Wis-non, a citizen of the United States, residing at Chicage, in the county of Gcok and State of Illinois, have invented certain new and useful Improvements in. Automatic Stripping and Tipping Devices, of which the following is a description. a

My invention relates to that general class of devices employed in binding books and especially to means for jattaclnngthe end sheets to the end sections. 1 1

The object of my invention is to produce a simple, convenient, reliable and rapid device of the kind adapted to automatically paste and attach the end sheets to the end sections, thus entirely avoiding theslow and inaccurate hand work for all kinds of work that may be required in this portion ofthe binding operations.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown 1 and described, and more particularly pointed out in the claims. 1 p i In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts:

Figure 1 is aside elevationof one end of a my device With parts removed and broken away to more clearly show the construction. Fig. 2 is a plan view of the part cfuny device shown in Fig. 1.

Fig. 3 is a detail of a slightly modified form of mechanism for detaching the sections from the feeding pins of my device.

In the form shown my device comprises a receiving table 1 provided with suitable guides 2 and 3 for accurately controlling the lateral position of the sections on the table and preventing their a displacement when being operated upon. a p b An auxiliary table 4 is provided slightly above, and substantially arallel to the table 1, so that a section may placed upon the table 1 and suitable end sheets maybe placed upon the auxiliary table Aland held substantially parallel to and directly above the several sections on the table 1. The width of the auxiliary table 4: is slightly less than the operativeportion of the tablel so that a portion of the Section and of the end sheets will'project beyond the edge of the auxiliary table and may be pasted togather if desired without pastingtl e re: mail-li g s rface of the a jesset heet The guides 2 and 3 may be rigidly held in position In any desired manner. As shown the guide 2 is rigidly secured in position.

ablescrews 55 or other convenient means extendingthrough the brackets 6-6 upon the guide and engaging the table 1 thus securely clamping the brackets to the table. The distance betweentlie. guides 2 and?) is obviously controlled by the width of the section which it. is desired to operate upon. The auxiliary table 4 is preferably of suitablejwidtli to accomodate the narrowest section which it is desired tohandle in my dev ce and consists merely of a strip of steel or other suitable material rigidly connected by a bracket 7 to a paste reservoir 8 or other convenient part of the mechanism whiclris in turn provided with the rod 9 rigidly attached thereto and arranged to coiiperate with a bracket it) upon the table 1 to rigidly secure the reservoir in position topermit of its vertical"adjustment as desired. In the ;n.-eferred construction the auxiliary table is suitably spaced from the guide 2 and a paste distributing wheel 11 projects through the bottom of the reservoir 8. The lbvver edge of the distributing wheel 11 extends into the spaces between the auxiliary table at and guide 2111 position to contact with any sections positioned between the aides and passing between the table 1 an auxiliary table 4. In the preferred construction the distributing wheel 11 is rigidly mounted upon a shaft 12 which is in turn rotatably mounted in suitable bearings 14'1 1 upon the reservoir 8 with a sheave 15 rigidly attached to the shaft and connected by a belt 1601- other suitablemeans to a drive sheave 17 for rotating the distributing wheel. 1

Any suitable meansma be provided for feeding the book section along the tablel. In the form shown a groove 18 is provided extending longitudinally of the table 1 in= termediate the guides 2 and 3 in close proxirn ity to the edge of the auxiliary table 4 opposite the guide 2. pair of sprocket wheels 19 and 20 are rotatably mounted near the opposite endsofthe table 1 arranged to support "a chain or other flexible connector 21 between them with the upper portion of the chain positioned in the groove 18; The sheath, 19 isrigidly mounted upon a shaft 22 rotatablysupported in bearings 23 near its opposite ends. The sprocket wheel 20 is rigidly mounted upon a shaft 24 rotatably mounted in suitable bearings 25 25 upon the table 1. One end of the shaft 24 projects beyond the side of the table adjacent the guide 2 and the sheave 17 is ri idly secured to this projecting portion of the shaft. In the preferred construction suitable pins. or other convenient means are provided at suitable intervals in the chain 21. to receive abook section between them so that when the shaft 24 is rotated the several book sec tions willbe engaged by the pins and carried longitudinally of the table under the dis tributing wheel 11 and the auxiliary table 4:. The pins 26 may be ofany suitable form or construction and attached to the chain 21 in any suitable manner. In the form shown the pins 26 are each provided with a thread ed portion adapted. to engage a threaded opening in suitable portions of the chain 21 so that the several pins may be spaced at any desired intervals upon the chain and rigidly held in their adjusted position. Each of the pins is of sufiicient length to extend above.

the upper surface of the auxiliary table 4 and engage any end sheets or sections positioned upon the auxiliary table, thereby moving them longitudinally of the auxiliary table'immediately above the sections upon the table 1 with the rear end of the sections orsheets upon the two tables substantially in line with each'other vertically.

Suitable means are preferably provided for forcing the sheets or sections on the aux iliary table into contact with the pasted portions withthe sections on the main table.

I In the preferred construction a bracket 28 sprocket wheel 20. In the form shown in Fig. 1 a plurality of fingers 84 are rigidly secured to the sprocket wheel 20 in such a position that as the wheel rotates the several fingers will successively protrude above the surface of the table 1 andeach will engage and raise therear end of a sectioniabove the adjacentpin 26.

In the form shown in Fig. 3 the fingers .84 on the sprocket wheel 20 are dispensed with and anarm87 having an upwardly project ing portion 88 at its free end is. rigidly attachedto a shaft 89 which is rotatably mounted below the table 1.1 An arm 91 is also attachedto the shaft 89 and a bar 90 extends from the free end ofthe arm 91 to a point near the end of the roller 35. Suitable means are provided on the bar 90 to engage a portion of the roll 35 or other convenient means adjacent thereto to prevent verticalmovement of the free end of the bar 90 without interfering with its longitudinal. movement. A roller 92 is also provided near the free end of the bar 90 adjacent the roller 35 and a cam 93 is rigidly connected to the roller 35 and adaptedto engage the roller 92 to periodically oscillate the bar 90 longitudinally and thereby partially rotate the shaft 89. \Vhen this occurs the part 88 of the finger 87 moves upward through a suitable slot in the table 1 and engages the rear endof the book section on the table and forces the same upward sufiicientlyto clear the pins 26. The several parts are so proportioned and arranged that the movement of the finger 87 accurately corresponds with the spacing of the pins 26 so that the part 88 passes upward through the slot in the table 1 just before each of the pins 26 reaches the part 88.

Having thus described my improvement 1t is obvious that various immaterial modifications may be made in my device without departing. from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form or construction shown. l
